Fiber is an optimum immediate investment to carry networks to the “post-100 Mb/s era”
• Fiber network technology is well established and proven
• Fiber networks are highly reliable
• Fiber networks reduce operating costs
• Fiber networks have the smallest carbon footprint of access network technologies

Current fiber network architectures are upgradeable for technologies taking us in to the 100 Mb/s era
• Fiber networks have the strongest transmission capability
• Fiber network standardization is established well past GPON
• Developing standards drafted (or envisioned) to leverage current fiber product and invested Plant
• Fiber networks are compatible with all other access network technologies

Current fiber network architectures are scalable for technologies taking us beyond the 100 Mb/s era
• PON support of 4G wireless
• Reach extension - 60 km reach or more
• WDM PON - A wavelength to each customer
• RFOG

Fiber networks create infrastructure for Innovation and Investment up to and beyond the “100 Mb/s era”
• Fiber is ready for the 100 Mb/s era today
• Optical fiber access networks leverage current fiber product and invested Plant
• Fiber networks are compatible with all other access network technologies
• Fiber networks complement other access network technologies in cases they are a better solution
• Fiber networks are the optimum baseline infrastructure for extending broadband and developing new and improved applications

• Since 2004, the cost to deploy FTTH has dropped about 45%
• It now costs network providers about $1,450 to bring optical solutions direct to your home.
• Due to the adoption of new technical innovations we expect deployment costs to continue to decline to $1,300 by 2010.
